KSH2955TM Equivalent & Substitute Parts

Part Overview

The KSH2955TM is a PNP bipolar junction transistor manufactured by onsemi, rated for 60 V collector-emitter breakdown voltage and 10 A maximum collector current in a surface mount DPAK package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts must maintain electrical performance within the specified parameter ranges while offering active product status and current manufacturing availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KSH2955TM is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: PNP
• Collector Current (Ic) (Max): 10 A minimum
• Collector-Emitter Breakdown Voltage (Max): 60 V minimum
• Package / Case: TO-252-3 DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute Classification:

Direct Manufacturer Equivalents maintain all electrical specifications and differ only in packaging format or product status transition:

• MJD2955T4G: Active status, Cut Tape & Digi-Reel packaging
• MJD2955G: Active status, Tube packaging
• NJVMJD2955T4G: Active status, Tape & Reel packaging

Parametric Equivalent (STD2805T4): Differs in collector current rating (5 A vs. 10 A) and power dissipation (15 W vs. 1.75 W). This part is listed as a similar alternative but does not meet the 10 A current requirement and is not a direct substitute for applications requiring full 10 A capability.

Engineering Selection Recommendations

Recommended Direct Substitutes for KSH2955TM:

MJD2955T4G, MJD2955G, and NJVMJD2955T4G are full electrical and mechanical equivalents manufactured by onsemi with active product status. These parts maintain identical electrical specifications including 10 A collector current, 60 V breakdown voltage, and 1.75 W power rating. Selection among these three should be based on packaging and supply chain requirements:

• MJD2955T4G: Suitable for automated assembly with Cut Tape & Digi-Reel packaging
• MJD2955G: Suitable for manual assembly or lower-volume applications with Tube packaging
• NJVMJD2955T4G: Suitable for high-volume production with Tape & Reel packaging

All three substitute parts offer extended operating temperature range (-55°C to 150°C) compared to the KSH2955TM (150°C maximum), providing improved thermal performance margin. All maintain ROHS3 compliance and MSL 1 rating.

STD2805T4 Consideration:

STD2805T4 is not recommended as a direct substitute due to reduced collector current rating (5 A vs. 10 A) and different electrical characteristics. This part is suitable only for applications where maximum collector current does not exceed 5 A and where the higher power dissipation capability (15 W) and transition frequency (150 MHz) are not required.

Frequently Asked Questions (FAQ)

Q: Can MJD2955T4G replace KSH2955TM in existing designs?

A: Yes. MJD2955T4G maintains identical electrical specifications for collector current (10 A), breakdown voltage (60 V), saturation voltage, and power rating (1.75 W). The DPAK package and surface mount configuration are identical. The primary difference is product status (active vs. obsolete) and packaging format (Cut Tape & Digi-Reel vs. unspecified).

Q: What is the difference between MJD2955T4G, MJD2955G, and NJVMJD2955T4G?

A: These three parts are electrically identical. The differences are in packaging format only: MJD2955T4G uses Cut Tape & Digi-Reel, MJD2955G uses Tube, and NJVMJD2955T4G uses Tape & Reel. Selection depends on assembly equipment and supply chain logistics.

Q: Why is STD2805T4 listed as a substitute if it has only 5 A current rating?

A: STD2805T4 is listed as a parametric equivalent based on matching voltage rating (60 V) and DPAK package. However, the reduced collector current (5 A vs. 10 A) and different electrical characteristics make it unsuitable for applications requiring the full 10 A capability of KSH2955TM. Use STD2805T4 only in applications where maximum collector current does not exceed 5 A.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (MJD2955T4G, MJD2955G, NJVMJD2955T4G, and STD2805T4) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the operating temperature range difference?

A: KSH2955TM specifies 150°C maximum junction temperature. MJD2955T4G, MJD2955G, and NJVMJD2955T4G specify -55°C to 150°C operating range, providing improved low-temperature performance. STD2805T4 specifies 150°C maximum, matching the original part.

Q: Can I use these parts interchangeably in PCB assembly?

A: Yes, for the three onsemi equivalents (MJD2955T4G, MJD2955G, NJVMJD2955T4G). All use identical TO-252-3 DPAK package with 2 leads plus tab. Pin configuration and footprint are identical. Packaging format differences (tape, tube, reel) affect only supply and handling, not PCB compatibility.
